Sanitary Napkins / Tampons vending machine

I would like to see an automated Sanitary napkin/ Tampon machine installed at each and every Public/Private Restrooms since to my dismay our international prestigious airports themselves are lacking such a facility that prompted me to insist on this idea. Just like any automated vending machine even sanitary napkins should be available in India especially since we are 2nd largest populated nation. And would be a big relief for women who are frequent travelers and working.
